If I set min_size=k+1, does that mean I'd need a minimum of m=3 to avoid loss-of-write with a 2-node failure?
Yes.
And to avoid loss-of-write with a 2-node failure, would I need: a) a minimum of k+m nodes, or
This is the bare minimum for EC without any recovery location.
b) a minimum of k+m+2 nodes?
This is recommended because with this number of nodes the cluster still has "spare" nodes to recover to in case of a node failure.
